Abstract

In un pneumatico per autoveicoli, specialmente per veicoli destinati all'autotrasporto pesante, il disegno battistrada comprende almeno quattro file di tasselli sostanzialmente della medesima larghezza, rispettivamente delimitati da almeno tre scanalature circonferenziali di diversa larghezza, le due più strette essendo disposte lateralmente, da parti opposte del piano equatoriale del pneumatico, in posizione assialmente esterna e da una pluralità di scanalature trasversali oblique colleganti coppie di scanalature circonferenziali adiacenti.La scanalatura stretta che separa le due file laterali di tasselli su ciascuna spalla del pneumatico ha una larghezza non superiore a 2,5 mm ed una profondità non superiore a quella delle scanalature trasversali confluenti mentre i tasselli di dette due file laterali sono circonferenzialmente scalati fra loro cosicché ogni tassello di ciascuna fila si affianca a due tasselli consecutivi della fila adiacente.
